So much for her "mediocre" lifestyle: Mila Kunis is reportedly on vacation in Bali with rumoured boyfriend Ashton Kutcher.

The former "That '70s Show" co-stars are shedding the pressures of Hollywood at a plush five-star resort in the south of the Indonesian island, according to the New York Post.

"Ashton was Mila's first kiss while on 'That '70s Show,' so they've always had a special bond," a source told the paper. "They started dating in the spring, and things have recently become more serious."

In August, Mr. and Mrs. Shawn Carter will rent a 31,000-square-foot estate in the Hamptons for $400,000, according to the New York Post. The house's monthly rent is $128,000 higher than the 2010 average sales price of a U.S. home.

The $43.5 million dollar abode comes with ample amenities — rock-climbing wall, recording studio, two-lane bowling alley, virtual golf and skateboard half-pipe.

The 60-foot heated pool is equipped with an underwater stereo system. It also has a gym, spa, combo basketball, racquetball and squash court, and garage that can store eight cars.

The master bedroom suite is 2,800-square-feet, bigger than most homes. And while the 11-acre property is large enough to accommodate guests, the lot includes a separate two-bedroom apartment.

When you're rich and famous, spending the summer in the Hamptons or Malibu just seems so pedestrian these days. Any real celebrity worth her weight in Christian Louboutins knows the place to be is a sun-drenched spot in Europe. Over just the last six weeks we've seen Naomi Campbell dancing through the streets of Southern Italy, Ryan Seacrest yachting around the French Riviera, Jessica Alba tweeting from a lounge chair on the Amalfi Coast, and Kim K. and Kanye hitting up Fashion Week in Paris.

Katy Perry may be a "California Gurl" at heart, but this past weekend she was spotted lounging poolside on vacation in Miami -- and she wasn't alone. Renowned crooner/heartbreaker John Mayer made sure this recent divorcee didn't get too lonely, witnesses say.

The pair reportedly had a brief fling in 2009, but as we all know, Perry went on to marry British comedian Russell Brand in 2010, divorcing him two years later. Mayer, on the other hand, hasn't exactly been pining over the Perry; he's been romantically linked to Jennifer Aniston, Jessica Simpson, and Taylor Swift.

When you have a schedule as hectic as Rihanna's, who wouldn't need a vacation? But the pop star's Mediterranean yacht trip with some gal pals is looking less and less like a retreat, and more and more like a second job.

Rihanna's itinerary on her trip has been go-go-go, right from the start. She began with a shopping trip in Sardinia, Italy, moved on to jet skis, beer, and a water trampoline in St. Tropez, and most recently parasailed in Cannes. RiRi seems to have found very little time for any actual rest and relaxation.

The family that plays together stays together! If happy couple Ben Affleck and Jennifer Garner looked like they were thousands of miles away from the Hollywood hustle and bustle this week, it's because they were! The duo had tons of fun in the sun with their three kids on a beach in Puerto Rico, where Affleck is shooting the drama "Runner, Runner" opposite Justin Timberlake.

The couple was snapped splashing around in the Caribbean water with daughters Violet, 6, and Seraphina, 3. A shirtless Ben showed off a hefty upper-arm tattoo while Jen — who gave birth to the couple's newest addition, son Samuel, five months ago — donned a black one piece and shades.

Later, the 40-year-old mom of three threw a striped sundress over her suit and carried baby Samuel for a walk along the water's edge. Hey, if the kid can't swim, he can at least get close to the ocean in his mama's arms!

And if the Garner-Affleck clan looks unusually normal to you (by Hollywood standards, anyway), you're not alone. The couple has actually made headlines over the years for seeming more average-American than showbiz-special, whether it's attending a local town parade with their kids, dressing down during public outings, or just the fact they've actually stayed together longer than many of today's celebrity couples.

Nicolas Cage has always been a little different, so it's no real surprise that during a pool outing with his wife and young son at their hotel in Italy's Amalfi region on Monday that he was covered up from neck to toe in a sport coat, jeans … and white sneakers. (Could this have anything to do with the reports that Cage is actually a centuries-old vampire?) The "Ghost Rider" actor allowed his face to get a little sun as his wife of nearly eight years, Alice Kim, tanned herself in a purple bikini and their 6-year-old son Kal-El dove in and out of the water wearing swimming goggles.

It's been a rough few weeks for Rihanna since the death of her beloved grandmother, but she's finding a reason to smile again. The "Where Have You Been" singer let loose on the water in Barbados with her friends and family on Thursday, boating, tubing — and drinking some beer. Seeing Rihanna have some fun is a welcome sight since she's looked so glum since her grandmother Clara Braithwaite lost her battle with cancer in a New York City hospital last month. After a memorial service in Brooklyn, Rihanna and her family buried GranGranDolly, as she was nicknamed, in their native Barbados on Tuesday.
